VSpecification fonming part of Letters Patent No. 3I,J"2v9, datedJanuary 29,1861.

T0 all whom it may concerter State of New York, have invented a new and Improved Grain and Grass Harvester; and I do hereby declare that the-foilowing is a full,l clear, and exact description of the saine, refer-l ence being-had to the annexed drawings, mak-- ing a part of this specification, in'which- Figure 1 is a side sectional view oi my invention, taken in the line xc, Fig. 3; Fig. 2,

a front sectional view of the same, taken in,

theline y y, Fig. Fig: 8, a plan or top View` of the saine.

, Similar letters of reference indicate Vcorrespending parts in the several figures.

The object ot' this invention is to obtain a simple, economical, and vefficient' means for elevating the iinger-bar and `sickle .to enable them 'to pass over obstructions that may lie in their path, and. also to enable the machine to be drawn from place to place, the parts being so arranged that the driving mechanism will be automatically thrown out o f gear as the ringer-bar and sickle areraised and' thrown in gear as they are depressed or allowed to descend to their working position.

To enable those skilled in the' art to fully understand and construct iny invention, l will proceed to describe it.

A represents the main frame of the inachine, which is of rectangular forni, and has the drivingwheel B fitted within it. To the back part of the ina-in frame A 'a bar, C, is

attached at right angles, and to the outer end of bar C there is attached a bar, D, which is parallel to the frame A. The main v'frame A, with thebars C D, constitute the whole of the framing of the machine, and to the bar D a Wheel, E, is affixed, the axle a of which is in line with the ,axle b of the wheel '13.' The wheels B E are of the saule diameter; but the driving-wheel B is broader than the other, E, in Fig. 3, the driving-wheel .being necessarily vbroad in order to obtain sufficient traction to 4drive the working parts.

"To the front part of the main frameAthere is attached by joints or yhinges a a, two bars,

y bt, to meandersiderof which a. mbe, F, -is Be it known that I, G. G. DicKINsoN, of' Poughkeepsie, in the county of'Dutchess and secured, and a bar, c, is connected bya hinge or joint, d, lto the front end'of the bar D, the

bar c having a pendentplate, e, secured to it.` To thelower end of the plate e andthe tube .E the iinger-bar'G is attached. This fingerbar maybe'constructed and' arranged in the` usual way, andtherefore does not require-a minute description., v

The sickle `is alsoplaced on the migrerbar, as `usual, andthe lsickle-bar f is attached at f one end :by a link, 'g, ,to -the lower part of a right-angle lever, 1E[,.whichfis fitted' inthe tube F at its lower partjas shown clearly in Fig.2. W

In the'upper part of the tube F there is placed a pinion, h, the shaft o3 of which pro-i jects through the 'sides of the-tube. end -of the shaftz' there is attached ahy-wheel, j, which 'also lserves as a erank-4 wheel, and communicates motion to the lever H, and consequently to the sickle, by means of a connect inermi, j p

Whe'n the machine is at work, the pinion h gears .into a wheel, k, which isplaced in' the main frame A, and has on 'its shaft Z apin-I ion, m, into which a toothed rim, n, gears, the rima being attached concentricallyto the drivf ing-wheel B. y

To the outer side of the inner bar, c, 'there is secured a toothed segment, I, and a lever, J, is also attached to said bar a. 4 i j K is a hook which is attached to theiinner bar, a, and which may catch into either of the teeth of the segment 'I and retain the iinger-bar and sickle at a greater or less height', as may be desired.' The driver, it will be seen, may at any time, by grasping thev lever J, elevate the finger-bar and sickle on `ac` count of the bars .a c and c being connected to the main frame A and bar D by joints or hinges; and it will also be seen that when` the parts aforesaid are elevated the pinion h will leave the wheel k, and the sickle will be rendered inoperative, the pinion it falling into `gear with wheelA 7c, when the iingenbar and sickle descend totheir Aproper working position.

To one- .e A amine v l The s'hoes Il L may be attached to bars MM', barf, lever H, `pinioixs hala, segment I, bar K, secured, respectively, tothe under side of the and lever' J, whenv the aboye parts are' coumain frame A and bar D. structed and arranged to operate substantially f Havingthusdeseribed my invention, Whatl as herein .shownr and described'. claim as new, and desire to secure' by Lettere` CHARLES G, DICKINSON.
